Summary
ImageCompliance, an automated tool, verifies computed tomography (CT) and magnetic resonance imaging (MRI) parameters for radiotherapy planning. This ensures accurate imaging protocols, improving patient safety and treatment effectiveness.
Area of Science:
- Medical Physics
- Radiotherapy Technology
- Image Analysis
Background:
- The importance of imaging in radiotherapy is growing.
- Verifying imaging parameters before treatment planning is crucial for patient safety and effective treatment.
Purpose of the Study:
- To develop and implement an automated script, ImageCompliance, for verifying CT and MRI parameters in radiotherapy planning.
- To ensure adherence to imaging protocols and improve workflow efficiency.
Main Methods:
- Developed ImageCompliance, a GUI-based script for automated verification of CT and MRI parameters.
- Integrated a centralized database to eliminate manual uploads.
- Implemented a multi-tier warning system for deviation identification.
Main Results:
- ImageCompliance has processed over 48,000 CT and MRI studies.
- Workflow inefficiencies were reduced by eliminating manual uploads.
- The warning system enabled timely identification of protocol deviations, supporting clinical decisions.
Conclusions:
- ImageCompliance enhances governance over imaging protocols in radiotherapy.
- It safeguards geometric and dosimetric accuracy, informing margin selection.
- The tool is an effective strategy for verifying CT/MRI imaging protocol compliance in radiotherapy.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
